Forklift battery info

Here's a little info I got from trying to find out info on my
forklift. My battery part number is stamped on one of the lead
crossbars near the positve terminal. The numbers stamped into the
side of the steel case (BB1 HL149) are meaningless I guess.

My P/N is 18 7523, which was explained to me as this, first two
numbers "18" indicate the number of cells. IE 18 cells = 36 volts.
Last two numbers are the number of plates in the battery, "23" Each
cell will start and end with a negative plate, so the number of
negative plates will always be an even number and one more than
positve plates. This means my battery will have 12 negative plates
and 11 positve plates in each cell. The "75" number is AMP/HR rating
of each positve plate. 11 plates times 75a/H per plate gives me a
battery of 825 A/Hr. total capacity.

Which seems to make sense beacuse there is a 825 stamped right under
the 18 7523.

You then need a charger rated to match the battery A/Hr rating so you
can charge the battery in 8 hours, give it 8 hours cool down and then
get an 8 hour work shift out of it.

This lift will see only occasinal use so I'm not worried about
matching up a charger.

Hope someone finds this trivia useful.

Thank You,
Randy
